RE: [google-appengine] Re: Entity size and latency

>Question is now is there some difference in get latency between 500 bytes or 10kb entites. Yes. And it seems to be about 72Megabits per second the last time we ran a bench mark. We haven't run it in a while. But for 500bytes and 10kb, I don't think you'd see much difference. 900k you do.

Re: [google-appengine] Re: Entity size and latency

The difference should be negligible. While you may have to worry about serialization issues in Python, the Java GC is quite efficient. I'll bet Go is pretty fast at that kind of thing too :-) Jeff On Wed, Feb 15, 2012 at 2:53 AM, Matija wrote: > Hi Robert, > I am actually doing some analysis

Yes. A completed transaction on EntityA will be guaranteed visible to a subsequent transaction on EntityA. If there is overlap, the second transaction will see ConcurrentModificationException. Jeff On Wed, Feb 15, 2012 at 12:21 PM, peterk wrote: > I've been looking around on this and it all s

Re: [google-appengine] A question about eventual consistency/transactions

Jeff, I've read a couple posts from others saying that indexes aren't update immediately and so you won't see newly created entities in a query when processing a subsequent request. Are they talking about queries outside of a transaction? There sure does seem to be a lot of confusion regarding

Cheers Jeff, that's a relief. As a follow-up... if I have multiple fetch/modify cycles on models within an entity group in a transaction, the fetches won't always necessarily show up-to-date models, right? E.g. within a transaction if I get modelA, update it, put it, then get it later in the tran
